GREASE GUN AND LIKE APPARATUS.

Application filed November 26, 1923. Serial No. 677,111.

To aZZ whom it may concern:

Be it known that 1, CHARLES Enro MILNER. a British subject, residing in the city of Birmingham, England, have invented cer tain new and useful Improvements Relating to Grease Guns and like Apparatus, of which the following is a specification.

This invention relates to lubricating apparatus, particularly of the kind ordinarily known as grease guns.

The object of the invention is to provide improved means for charging or filling such apparatus with grease.

The invention comprises a system of radially disposed strips or blades, and a cap or the like through which the blades can slide, as hereinafter described.

In the accompanying sheet of explanatory drawings Figure 1 is a side elevation of a grease gun filling device constructed in accordance with this invention.

Figure 2 is a sectional plan of the same.

Figure 3 is a part sectional side elevation showing the filler in the body of a grease gun.

Figure 4 is a sectional plan showing a modified construction of the filler.

In carrying the invention into eii'ect as shown in Figures 1-3 of the drawings.

My improved charging or filling device consists of a system of three, four or other suitable number of metal strips or blades a which are grouped together so that when viewed endwise they occupy a radial relationship to each other. The form illustrated consists of four blades arranged at right angles. The strips may be separate from each other, or their adjacent longitudinal edges may be in contact, or they may be formed integrally. Alternatively a single metal strip may by corrugating or bending be shaped to provide the required radial system of strips or blades as shown in F igure 4. At one end a handle I) is provided,

and on the blade is slidably mounted a disc or plate or cap 0, the latter being slot-ted to fit over the blades. If desired the plate may be flanged to fit over the open end of the cylindrical body of the grease gun. The

flange may also be screwed internally as shown so that it can be secured to the screwed end of the body d. On the ends of the blades small projections e are formed to prevent withdrawal of the blades from the part c. Preferably the upper ends of the blades are extended at e to form stops which can abut against the outer side of the cap.

In use the part c. is moved to the handle end of the blades, and the latter are pressed into a quantity of grease contained in an ordinary storage receptacle. Rotation of the device causes the grease in the spaces between the blades to adhere to the blades and be separated from the bulk. On withdrawing the device it carries with it the grease adhering to the blades.

The charged device is then inserted in the empty body of the grease gun as shown in Figure 2, and the part c is held against or secured to the open end. The blades are then withdrawn through the plate and the grease is left behind in the gun.

The invention is not limited to any particular constructional details, as these may be varied in a number of ways. Also the invention is not limited to use with grease guns as it may be applied to other like purposes.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is '1. Means for charging or filling grease guns and like lubricating apparatus, comprising a system of radially disposed blades, and a cover through which the blades can slide, substantially as described.

2. A filling or charging device for grease guns and'like lubricating apparatus, comprising a plurality of radially disposed blades, a handle at one end of the blades, a slotted cover through which the blades can slide, and means on the inner end of the blades for preventing detachment from the cover, substantially as described.

In testimony whereof I have signed my name to this specification.

CHARLES ERIC MILNER.
